Kingdom Plantae - Kingdoms Slideshow

The next set of plants in our show has developed the ability to produce seeds. Gymnosperms such as conifers and cycads produce naked seeds. Angiosperms that include all flowering plants are able to produce seeds with one or two seeds coats.

Conifers produce cones that hold seeds until they are
ready to release into the wind. They are able to sexually reproduce
when wind spreads pollen to neighboring cones. Flowering plants use a
variety of methods to reproduce. While some species use wind, many
others rely on insects to spread pollen from one flower to another.
Some species are so specialized that they can only be pollinated by one
species of insect. If that insect is not around, the plant species will
eventually become extinct.
